Don't print stats for unrecognized players

Or anything else, really... just assert that a player has some scores when parsing their username

Reopening for investigative purposes.

This appears to work fine for everyone except for 'squadxzo', no caps - his name is supposed to be capitalized ('Squadxzo'), but asking for other improperly-cased names is no issue (eg. 'Golfkid' properly says 'no scores').

This really isn't a huuuuuge problem, but very curious :)
